Design constraints that have so many factors that people still don't use autorouters for most stuff. You're not getting it, drawing the wires isn't the hard part, understanding the constraints is.
replyI think we agree with that part.
replyI once thought software constraints were so hard a machine would never be able to program it.
But on the other hand, there are tons of circuit boards designed day after day. If it was super hard, we'd not be able to have the tens of thousands of high speed motherboards that come out year after year.
So "not everything happen or could be done in literal languages" is the part that got you?
reply18ghz circuits were around since 1973 was the part that got me.
replyYour response doesn't really add to the conversation so I'll stop here.
